We divide 3419799 by 800
We want to divide 3419799 by 800.

Advancing to step 1:
When dividing 3 by 800, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 800

Let's proceed to step 2:
800 can be fit into 34 0 times, resulting in a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Fetch the next digit (1) from the dividend, attach it to 34 and continue: 341 / 800

On to step 3:
800 goes into 341 0 times with a remainder of 341.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 341 and we're left with 341.
Grab the next digit (9) from the dividend, add it to 341, then carry on: 3419 / 800

Let's proceed to step 4:
800 can be fit into 3419 4 times, resulting in a remainder of 219.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 3200 away from 3419, we end up with 219.
Grab the next digit (7) from the dividend, add it to 219, then carry on: 2197 / 800

Advancing to step 5:
2197 divided by 800 is 2 with a remainder of 597.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Subtracting 1600 from 2197 leaves us with 597.
Bring next digit (9) of the dividend behind the 597 and repeat the process: 5979 / 800

Step 6:
800 goes into 5979 7 times with a remainder of 379.
Put 7 as the next digit of the answer. 
Result so far: 427.0
Deduct 5600 from 5979 and we're left with 379.
Fetch the next digit (9) from the dividend, attach it to 379 and continue: 3799 / 800

Advancing to step 7:
The number 800 fits into 3799 4 times, leaving a remainder of 599.
Record the quotient 4 as the next digit in the result. 
Result so far: 4274.0
Subtract 3200 from 3799 to get 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Let's proceed to step 8:
5990 divided by 800 is 7 with a remainder of 390.
The number 7 becomes the next digit in our result. 
Result so far: 4274.7
If we subtract 5600 from 5990, we get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Moving on to step 9:
800 goes into 3900 4 times with a remainder of 700.
Record the quotient 4 as the next digit in the result. 
Result so far: 4274.74
The remainder is 700 after subtracting 3200 from 3900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Let's proceed to step 10:
If we divide 7000 by 800, we get 8 and a remainder of 600.
Write down 8 as next digit of the result. 
Result so far: 4274.748
Subtract 6400 from 7000 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 11:
The number 800 fits into 6000 7 times, leaving a remainder of 400.
Write down 7 as next digit of the result. 
Result so far: 4274.7487
If we subtract 5600 from 6000, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 12:
800 can be fit into 4000 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 4274.74875
Subtract 4000 from 4000 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 13:
800 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4274.74875
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 14:
800 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4274.74875
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 4274.74875, with a leftover of 0.0.
